CDOT will try to make driving on Colfax Blvd. in Jefferson County a little easier.

Starting this week, crews will be making repairs and improvements on Colfax between I-70 and Cole Blvd. and from Simms St. to Kipling St.

The project costs $2.9 million and will shut down one or two lanes, depending on the time of day.

CDOT says normal work hours at the project will be 7 a.m. to 3:30 p.m., Monday through Friday. They will also work overnight, between 7 p.m. and 5 a.m.
